You can use the existing iLiad templates (blank, lines or squares) or you can create your own. There's several templates that are user-created available here at MR.

You can download a free 30 trial of MyScript Notes from iRex and test it on your handwriting. If you wish to purchase it after the month, you pay online for an unlock code.
